Abstract

The plastic screw cap (1) that closes the injection and / or discharge connection of the liquid storage and transportation container is equipped with a bung (2) integrally combined with a venting and inflation device (3), a sealing cap (4) and a screw cap ( 1) Protective cover (5) that covers completely and prevents contamination.

Description

technical field [0001] The invention relates to a screw cap with a cover plate, a cover rim attached vertically to the circumference of the cover plate, a bung adapter (Spundstutzen) and a sealing cap covering the bung (Spundstopfen), wherein the cover rim has Internal thread to close the injection and / or extraction connection of the liquid storage and transportation container; bung for device or vent / inflate device. Background technique [0002] Disadvantages of the screw caps disclosed by EP0650446 B1 for closing the injection nozzles of plastic liners of bung barrels or tray containers with grid or sheet shells are that dirt deposits on the cap surface, and When the container is left in the open, rainwater collects in the basin-shaped recess of the cover plate for receiving the bung nipple. Contents of the invention [0003] The object of the present invention is to improve screw caps of this type from the point of view of avoiding the deposition of dirt on the cap su...
